Eudora unable to update the system registry. Your default mail program has not..

[Anthony]

Hi

I'm having the above message when accessing Eudora mail
when logging on as a domain user, even though I'm still
able to use Eudora. The machine that I'm using are having
multiple Eudora directories for different users. Out of
the few Eudora accounts, only one of them are able to
access the mail without the message.

If I login as administrator, all are able to login
without the message. How to resolve this issue?
